Ditching your ovalised chainring

[novetan]

Anyone so far not happy with the performance of an ovalized chainring and change back to the normal round ring. Pretty sure you convert to ovalised ring after reading all the reviews, hype, rumour, etc, but be done with it. What’s your reasons?

No difference to performance in my case and front shifting can never be as crisp as it is with round rings.

Had one fitted when I bought the bike. No problems, is it better or worse - not sure. Would I bother changing,- not untill it's worn out. Changing gear - not trying to win the TDF so it seems fine.

I have run ovalized chain rings and believe that they function as intended to some degree, however the shifting performance and quality is nothing short of dire imho and it was this which made me drop them.
I would likely use them on a TT bike for a flat course, but not on a road bike again.

Are they any good on a fixie?

Shimano tried it with Biopace.

I've just realised how old I am - apparently they stopped making them in '93!

I've got a 105 biopace chainset down my cellar. I was using it a couple of years ago

The new rings are fundamentally different to biopace. Not that that really makes much difference, but don't confuse biopace with q-rings/osymmetrics.
